Halfway Between 67 and 990

When you ask "What number is halfway between 67 and 990?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=67 and Y=990.

Halfway Between Line

To find the number halfway between 67 and 990, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 67 and 990 into our formula, we get:

(67 + 990)/2 = 528.5

Thus, the number halfway between 67 and 990 is 528.5.

To check that our answer is correct, we subtract 67 from 528.5 and subtract 528.5 from 990 and compare the two numbers:

528.5 - 67 = 461.5
990 - 528.5 = 461.5

As you can see, the halfway number is 461.5 higher than 67 and 461.5 lower than 990. Therefore, our halfway between answer of 528.5 above is correct.
